Supporting Conceptual Awareness with Pedagogical Agents
This paper describes a series of efforts in building and conceptualizing software agents for distributed collaborative learning. The agents are referred to as pedagogical agents. We have integrated pedagogical agents within two collaborative environments, TeamWave Workplace and Future Learning Environment. The role of agents in these environments differs from past work on software agents in their function as extended awareness mechanisms, focusing on task and concept awareness (conceptual a
A symbolic manipulator to introduce pupils to algebra theory
Within the theoretical framework of Vygotsky's theory, the paper presents a new algebra software. The main features of the software are described and their potentialities are discussed. According to the Vygotskian theory, expressions and commands may be thought as external signs of the Algebraic theory, and as such, they may become instruments of semiotic mediation: In other terms they can be used by the teacher, in the concrete realisation of classroom activity, according to the motive of intr
Get Me Off This Planet
The purpose of this lesson is to teach the students about how a spacecraft gets from the surface of the Earth to Mars. The lesson first investigates rockets and how they are able to get us into space. Finally, the nature of an orbit is discussed as well as how orbits enable us to get from planet to planet — specifically from Earth to Mars.
Red Rover Robotics
This lesson begins with a brief history of robotics, describing how robots are beneficial to engineering and society and then explores how robots have been used in recent space exploration efforts. The engineering design of the two Mars rovers, Spirit and Opportunity, are examples of advanced engineering design for space research. The maneuverability of these two spacecraft's robotic arms and the functionality of their tools is discussed.
Just Passing Through
This lesson helps students explore the functions of the kidney and its place in the urinary system. Students learn how engineers design instruments to help people when kidneys are not functioning properly or when environmental conditions change, such as kidney function in space.
The Heart of the Matter
This lesson describes how the circulatory system works, including the heart, blood vessels and blood. Students learn about the chambers and valves of the heart, the difference between veins and arteries, and the different components of blood. This lesson also covers the technology engineers have developed to repair the heart if it is damaged. Students also understand how the circulatory system is affected during spaceflight (e.g., astronauts lose muscle in their heart during space travel).
The digestive system is amazing: it takes the foods we eat and breaks them into smaller components that our body can use for energy, cell repair and growth. This lesson introduces students to the main parts of the digestive system and how they interact. In addition, students learn about some of the challenges astronauts face when trying to eat in outer space. Engineering helps figure out how to deal with such challenges.
Our Amazing Skeleton
This lesson covers the topic of human bones and joints. Students learn about the skeleton, the number of and types of bones in the body, and how outer space affects astronauts’ bones. Students also learn how to take care of their bones here on Earth to prevent osteoporosis ─ or weakening of the bones.
Move Your Muscles!
This lesson covers the topic of muscles. Students learn about the three different types of muscles in the human body and the effects of microgravity on muscles. Students also learn how astronauts need to exercise in order to lessen muscle atrophy in space. Students discover what types of equipment engineers design to help the astronauts exercise while in space.
This lesson introduces students to the space environment. It covers the major differences between the environment on Earth and that of outer space and the engineering challenges that arise because of these discrepancies. In order to prepare students for the upcoming lessons on the human body, this lesson challenges them to think about how their bodies would change and adapt in the unique environment of space.
Event-Driven Interoperability Framework For Interoperation In E-Learning Information Systems - Monit
Enormous efforts are put in both directions of the area of e-learning technologies- information and learning aspects. On one hand, there are new challenges in learning technologies, which tends to be in focus of research of the community of practise. On the other hand, there are learning specifications developments, which are technology oriented. And last, but not least new exciting technologies appear on the web. In order to achieve the primary goal in technology-enhanced learning - better lear
An Advisory QoS Service for GRID Based Learning Environments
This paper argues that the assumption of end-to-end QoS provision for use in Grid based applications is unsafe. We present an architecture which provides an adaptive QoS service for GRID applications which are prepared to adapt rather than assume the best and then suffer the worst. This is particularly relevant to Internet based GRIDs. An example application from the field of collaborative learning environments is given, featuring adaptive QoS for Real Time Protocol (RTP) based audio and visual
Choosing for learning objects: The possible deployment of learning objects with eight educational am
The Dutch six-part series Leerobjecten in de praktijk (Learning objects in practice) is about six divergent and difficult problems that occur frequently in working with learning objects. Based on research into existing practice, guidelines are offered to policy makers, educational technology consultants, teachers, educational designers and developers of digital learning materials who are struggling with these problems in higher education. Choosing for learning objects discusses eight education
Muscles, Muscles Everywhere
This activity helps students learn about the three different types of muscles and how outer space affects astronauts’ muscles. They will discover how important it is for astronauts to get adequate exercise both on Earth and in outer space. Also, through the design of their own microgravity exercise machine, students learn about the exercise machines that engineers design specifically for astronaut use.
Embedding knowledge in the design of an orthopaedic surgery learning
This paper deals with an ongoing work involving surgeons, didacticians and computer scientists. The objective is to design a computer based environment for learning screw placement in orthopaedic surgery on the basis of a computer assisted surgical (CAS) tool. We describe our methodology to create a didactical plug-in component for the CAS system. The created system will consider the user's knowledge employed for the task to provide linked and relevant feedback.
On-line Learning Networks: Frameworks and Scenarios
Progressively the idea of using the internet as a platform to mediate social interactions and learning at different levels has affirmed itself, and this has given rise to a huge number of spontaneous and planned collectives, which are often described as on-line learning networks. On-line learning networks create value from a combination of content and people knowledge. They can vary widely in the strength and permanence of their connections and resources necessary to maintain them. Aspects both
A Metadata Based Web Distance Learning Platform
Distance Learning is acquiring a role that becomes more and more important with the huge diffusion of the Internet and related technologies. Consequently, the investigation for adequate architectures and platforms supporting flexible Distance Le arning engines and solution is nowadays of great interests in the Scientific Community. The present paper introduces a platform based on the adoption of Metadata concepts and on the use of a “processorlike” behavior of the Web Course Delivery engine
Walk, Run, Jump!
In this activity, students participate in a series of timed relay races using their skeletal muscles. The compare the movement of skeletal muscle and relate how engineers help astronauts exercise skeletal muscles in space.
Hypertext navigation and conflicting goal intentions: Using log files to study distraction and volit
This paper describes a theoretical analysis and experimental investigation of difficulty related distraction by conflicting goal intentions in learning and problem solving with hypertext. Log files are used to capture hypertext navigation in the face of opportunities to implement competing goal intentions. We study how differences in task difficulty influence the volitional protection of the current goal intention. First attempts to integrate volitional processes of action control into cognitive
